Any one tried to use Adams idea to get over sticky spot?

Hi allcanadian and All,

Quote:..."It is weird that so many people read so many things into Wesley Gary's machines. When in his patents he tells you roughly how it works, but in a cryptic kind of way. Basically his neutral line with one magnet is bogus, I tried hundreds of combinations, But with two magnets in repulsion and a spring balanced shield it's a piece of cake. Try it you will like it."

I would like to add Ben Thomas and my own understandings on Gary's neutral line concept. I made some tests in 2003 when I first saw Ben's home page on his ongoing experiments. Earlier I read Gary's Canadian patent and as I understood, he suggested the best effect is with HORSESHOE magnets (though he left open the possibility of using other shapes of magnets.)   So I tested the neutral line' existance with a horseshoe magnet and with a rectangular piece of 20mm x 45mm, 3mm thick ferrite block. I did not make photos then from my work, but saved Ben's photos from his site and attached here. (His site does not exist now.)

In his first picture you can see the iron block placed exactly onto the neutral zone (Ben named it NZS line) and his Hall probe shows zero flux density (practically 0 Volt). This means that the iron does not show any magnetism received from the very near horseshoe!

In his second picture he moved the iron piece a bit above the NZS line (further away from the magnet) and the meter shows -0.131V , indicating a pole appeared on the iron piece.

And in his third picture he moved the iron piece below the NZS line (nearer to the horseshoe) and the meter shows +0.245V, indicating the appearance of the opposite pole on the same iron piece ending.

So the point is that easier to use horseshoe magnet to receive the neutral line than differently shaped magnets as you experienced.

Thanks for your ideas, especially the rotary LEMA, I like it. If you fill up the space on the rim of the washer with further magnets, you will get a symmetrical setup (in which the shield is supposed to rotate very easily) and you have to find clever ways to disturb the symmetry with the least amount of outside work. (Igor Knitel in this Forum showed similar shield-rotated setup with big ring magnets).

Hi All,

I would like to remark wrt the Wesley Gary concept that the soft iron (or ferrite) block can be positioned ABOVE or BELOW of the horseshoe endings, for neutral lines exist at those places too (the iron block is in FRONT of the horseshoe endings in the photos).

In Gary's Canadian patent the horseshoe magnet is drawn only in Fig. 5, and in the explanatory Figs. 1-4 only the endings of the horseshoe is drawn in a simply way, this is as I understand.

You can easily make a "horseshoe" magnet by using two rectangular block (or even cylinder) magnets and attach them to one side of a rectangular soft iron block, just near its endings, with opposite poles.
I understand that at the moment the horseshoe or the likely shaped magnet arrangements are perhaps not the best shapes for us at moment to directly use in setups like this thread is mainly involved.  With my contribution I wished to clarify more precisely Gary's neutral line concept.

Hi Craig

I had a look at the Takahashi /Wankel engine a while back. Still trying to suss out what is actually attached to the electromagnet that moves when the rotor hit top center.

I do not really see how it will get over the sticky point force.

Hi Clanzer,

Just a thought, what about using the stepper motor as the bearing on a takahashi magnetic motor? Smaller but maybe less work to knock up?

Hi Gyula

Excellent info, many thanks and very interesting.
This is defo going to be a good contribution to help ideas going around.

Regards

Sean.

Hi Clanzer and all.

as i understood it in the wankel, the electro magnet was just fired at top dead centre to push the rotor over the sticky spot, no mechanical movement as such. But having said that, look at the thread " Servo assisted magnetic motor, there is a nice video Jose did of his machine. In it he uses a modified servo motor to wiggle the top dead centre magnet and gets it spinning around nicely.
One wonders how many joules of energy you could get on 300 degrees of rotation, i might be wrong, but the wankel normally does not suffer a lack of torque so using stepper motor as bearing and generator would be a quick way of knocking something up. I have to think small unfortunatly as everything i have made so far has been made outside on a plastic patio table..LOL
